Light-up is an app that magnifies the resolution of image, which can make image in mobile phones look clearer. After selecting the photo and touch 'light-up' button, the program will be executed automatically. After the progress bar is read out, the picture processing is completed. For images with too much noise or manual processing (such as beauty, compression, sharpening,cropped), the processing effect may not be good. Light-up only supports selected image resolution below 1200*1200 now. The current AI processing time may be slightly longer than the progress bar reading end time.
